I Specification of Letters Patent. i ai;gnt d A 29 1922 Application filed August-6, 1920. Serial no. 401.68

To all whom it may concern:

Be it known that 1, JOHN PHIL. BANN'IGAN, a citizen of the United States, residing at Utica, in the county of Oneida and Stateof New York, have invented certain new and useful Improvements in Letter-Reproducing Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

' My invention relates to'a letter reproducing device, and I declare the following to be a full, complete and concise description thereof suflicient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification. I

The object of my invention is to provide a machine that will reproduce writings or drawings or any matters that can be perforated through a stencil, whereby a plurality of copies of a given subject mattercan be made for any desired purpose.

The invention comprlses a frame having a perforated circular base that is covered with an absorbent material, such as cloth adapted to retain ink thereon. Over this cloth, is removably held a paper or wax stencil that is perforated to conform with the subject matter to be reproduced. The stencil is held in place by certain members of a vertically movable'handle.

The object will appear by referring tothe drawings in which:

Fig. l is a perspective view of the device Fig. 2 is a central vertical-section taken on the'line 2-2 of Fig. 3; l

Fig. 3 is a top plan view of the letter reproducing device. Referring more particularly to the drawings, the device embodies a circular base plate +1 made of sheet metal and having perforations or apertures 2 arranged more or less in groups over its entire surface. The apertures 2 are adapted for the passage of ink to the absorbent cloth 3 therebelow. Furthermore, the lateral edges of the plate 1 are turnedup at an angle, as at 77,

in order to prevent the escape of ink past the sides of the plate 1-.

The free ends Jr-4E of the plate -1 are bent at an angle, whereby to form a horizontal plane. The cloth3 is stretched over the convex surface of the plate 1-- and its 7 free ends glued or otherwise fastened to the hor zontal parts of the ends d i of plate surfaceof the ends 14 of plate 1- Plate 5 is reinforced in the center part thereof by an annularmetal ring piece 6 that is spot welded to said plate 5. A screw threaded aperture is made in alignment through theplate 5 and ring piece 6 for the reception of a screwbolt 8that has attached to turn therewith an annular thumb piece. 9 having a, serrated periphery adapted to aid in turning said bolt 8. i i

The upper end of the bolt 8 is headed at 1 0. The head rests upon a washer 11 through which the shank of the bolt 8 pro 'jects. The head 10 of the bolt 8 and the Washer 11 are housed in a recess 12 made in the wooden handle 13. The washer llforms a bearing surface for the head 10 of the bolt 8 to turn on. The'recess' 12 is covered by a inetalplate 14 that is fastened to the wooden surface ofthe handle 13 by sharp points 15 thatprojectfrom the under surface of said plate 14.

The ends of the handle 13 rest in the metal rings 16l6 that are made integral with the brackets 1717. The free end of each of the brackets 17 is formed with a horizontal planesurface 18 adapted to lie in a plane parallel with the upper, surface of the ends 4&- of base plate 1-, whereby the ends,

of a paperorwax stencil 20 can be clamped between the under 'surface'of' the said mem here 18 and the ends of the cloth 3 that rests upon the horizontal 4-4 of plate l.

Thehandle 13 andfmembers 18 attached thereto are lowered and raised from full to dotted line position ,asshown in Fig.2, whereby to fasten or release theends ofa paper stencil 20 by turning the bolt 8 in the portions of the ends desired direction.

' The device is operated by first making a paper stencil 20 that conforms to the letter or other matter 'to'be reproduced and then fastening saids'tencil 20 upon the convex surface of the base plate -1 and over the absorbent cloth 3 by engaging the ends thereof between the "under surfaceof members 18-18 and the upper surface of cloth 3 that rests upon the ends 4: 4 of plate 1.

The thun'ib piece 9 will be turned to lower the members 18--18 and raise the plate against the lower surfaces of the-ends :4

' of plate 1, whereby to clamp the ends of the stencil 20 in this position. I

The stencil 20 will receive ink from the absorbent cloth 3, whereby to make an impression of the matter to be reproduced on the paper sheets, not shown, therebeneath, as the device is rocked thereover by means of the handle 13. In the event that certain portions of the stencil 20 leave a poor or dull impression of parts of the written matter on the stencil, more ink can be added to the cloth directly over said spots and without detaching said stencil 20 by placing ink prefe ably with a brush upon the near surface of the plate -1 and over said dull spots, whereby it will pass through the perforations 2 to the desired location on the absorbent cloth 3.

Stencil 20 can be re laced easily with another by turning the t umb piece 9 to raise and lower the members 18 off the ends of said stencil 20.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a letter reproducing device, a frame having a circular base, an absorbent cloth and stencil adapted to cover said base, means for permitting the passage of ink through said frame to said clot-h, the free ends of said frame being-bent to form a horizontal plane. a floating plate, a handle disposed in longitudinal position relative said frame,

and having brackets with plane surfaces, and a bolt for forcing the ends of said plate against the ends of said frame, whereby to clamp theends ofsaid cloth and stencil in place between. the floating plate and the plane surfaces of the brackets.

2. In a letter reproducing device, a frame having its free ends bent to form a horizontal plane, an absorbent cloth and stencil adapted to cover said base, perforations in said frame for the passage of ink to said cloth, the free ends ofsaid frame being bent toform a horizontal plane, a floating plate, a handle having brackets with plane sur faces and disposed in alongitudinal position relative to said frame, a screw bolt for forcing the ends of said plate against the ends of said frame. whereby to clamp the ends of said cloth and stencil between said floating plate and the plane surfaces of the brackets, andan annular thumb piece for turning said bolt. 1

3a In a letter reproducing device, a frame having a circular base forming a chamber, an absorbent cloth and stencil adapted to cover said base, perforations in said frame for the passage of ink to said cloth,the free a l-erase frame being bent to form it out 1 plane, a floating plate, a bolt i eaded to said plate, and an annular thumb piece for turning saidl bolt, whereby to clamp the ends of said cl'othand stencil between the floating plate and the plane surnices of the brackets.

4t. In a letter reproducing device, aframe having circular base with its sides turned form a chamber, an absorbent cloth cil adapted to cover said base, perrations in said frame for the passage of ink to said, cloth, the free ends of said frame being bent to form a horizontal plane, a fioating plate whose ends are adapted to make contact ith the ends of said frame, a handle disposed in longitudinal position with reference tosaid frame and having brackets with plane surfaces, a screw bolt carried by said handle, whereby to force the ends of aid plate and the plane surfaces of said brackets towards each other to clamp the ends of the cloth and stencil between id plane surfaces and the ends of the Ina letter reproducing device, a frame having a circular base, an absorbent. cloth and stencil adapted to cover said base, perforations in said frame for the passage of ink tois'aid cloth, the free ends of said frame beingbent to form a horizontal plane, a floating plate whose ends are adapted to make contact with the ends of said frame, a handle having brackets with, plane surfaces, screw bolt carried by said handle, whereby to force the ends of said plate to.- wards the plane surfaces of said brackets to clamp the ends of the frame, and an annular thumb piece carried by said bolt for turning the same.

G. In a letter reproducing device, a frame having a circular base with its edges turned up, an absorbent cloth and stencil, adapted to cover said base. perforations in said frame for the passage of ink to said cloth, the free ends of said frame being bent to form a horizontal plane, a floating plate whose ends are adapted to make contact with the ends of said frame, a handle disposed in longitudinal position with reference to said frame, brackets with plane surfaces for supporting said. handle, a screw bolt carried by said handle. whereby to force the ends of said plate towards the plane surfaces of said brackets to clamp theends of the cloth and stencil between said plane surfaces and the ends of the frame, an annular thumb piece carried by said bolt for turning the same, and said thumb piece being located adjacent said handle.

In testimony whereof I have affixed my signature.
